T0 0% whom it may concern/.-

Be it known that I, ERNST SENSBURG, a subject of the King of Bavaria,residing at Munich, Kingdom of Bavaria, Germany, have invented certainnew and useful Improvements in Type-Writers, of which the following is afull, clear, and exact description.

My invention relates to improvements in typewriting machines.

The object of my invention is to provide a type-writing machine whichwhile reasonably compact will permit of the use of a larger number oftype than usual, so that not only letters may be printed at one strokeof a key, but also syllables and words such as are in common use.

With this object in view and some others which will be obvious to thoseskilled in the art a machine embodying my invention comprises aplurality of type bar carriers or frames mounted on a carriage, eachprovided with a plurality of type-bars, each of which type-bars carriesa plurality of type, means being provided for positioning the type-barcarriers with relation to the printing-point and for positioning anydesired type-bar of the positioned carrier, whereby the desired type onthe type-bar is brought to the printing-point. Any suitable papercarrying and feeding mechanism may be employed and also any kind ofspacing device or printing mechanism.

My invention will now be described in connection with the drawings andthen particularly pointed out in the claims.

In the drawings, Figure l is a side elevation of so much of a machineembodying my invention as is necessary to illustrate the said invention;Fig. 2, a plan view of the same; Fig. 3, a detail perspective view ofone of the type-bar carriers or frames with the typebars, showing also apart of the means for positioning the type-bars.

Referring to the drawings, 1) b b b indicate a plurality of type-barcarriers or frames (in the present case four in number) mounted in acarriage B, movable along a track B. Each frame or carrier 1) b b b isprovided with a set of type-bars, each set consisting of a plurality ofmovable type-bars, in this instance three in number, as indicated at aa? a Fig. 3, each of which has a plurality of type, as indicated at a,Fig. 3. The typebars a a a are mounted to move in the respective carrierin the direction of their own lengths, for example, by providing slotsin the frame in which the said type-bars lie, the said type-bars beingheld in the slots in a mannerto permit of their longitudinal movement byany suitable meansas, for example, by undercutting the slots and makingthe type-bars of a corresponding cross-section, so that theywillproperly fit said slots. The sets of type-bars are so arranged in theirrespective frames that the axes of the typebars of each set willintersect at the printingpoint. For example, in the structure shown inFig. 3 the central type-bar a occupies a vertical position, while thetwo outer typebars a a are each arranged at an angle to the centraltype-bars, so that the axes ofthe type-bars would intersect at the pointat, Fig. 3, which is the printing-point. By this construction anydesired type on any one of the type-bars may be brought to theprintingpoint by moving the proper bar in the direction of its lengthfor a suitable distance. Furthermore, by moving the carriage B,containing the frames 1) to 19*, in the proper direction and to therequired extent any desired set of type-bars may be brought into theplane of the printing-point, whereby any desired type of any type-bar inany of the various sets may be positioned for printing. In the machineunder consideration the normal position of the type-bars a a a 'is withtheir upper ends below the printingpoint, and hence in order to positiona type for printing the bar carrying the desired type must be elevated.Therefore in the present machine I provide means for moving the carriageB and means for elevating the I typebars. The preferred mechanism fordoin this will now be described.

The carriage B, Fig. 'l, is connected ina suitable manner to theupperend of a lever e by means of a pin 6, secured to the carriage,which pin enters a slot in the end of the lever e. The latter isfulcrumed on the frame, as at 6 and is arranged to be moved inany-suitable manneras, for example, by a treadlelever E, connected by alink E to a bell-crank E which is joined by a rod E to thelower end ofthe lever e.

ing rods.

socket joint (indicated at S, Fig; 3)each rod being forced outward at anangle by means of a spring a a U3, secured at one end to its.

respective rod and at the other end passed loosely through a staple R onthe end of the type-bar. In order to prevent the springs u 11. n fromforcing the rods outward unduly and to insure the normal retention ofthe rods at'a predetermined angle to the type-bars, suitable stopdevices are provided, these consisting, preferably, either of a loopsecured to the type-bar, as shown at t in Fig. 3, or of fingers t 25which are secured to the respective type-bars and extend over thecorrespond- By this means the lower ends of therods r r r may beheld ina line with each other. The said lower ends are arrangedto be engaged bysuitable lifting devices--as,for example,the key-levers o 0 0 -each ofwhich is fulcrumed in the frame, as indicated at 0, Fig. 1, and isprovided with a socket 0, arranged to engage a ball on the lower end ofthe corresponding lifter-rod.

For the purpose of operating the levers 0 0 0 the predetermined extentnecessary to bring the various types to the printing-point a number ofplunger-keys p 19 19 Fig. 2, are provided, these keys being preferablyarranged in banks, as shown in Fig. 1, each bank being at a differentdistance from the fulcrum of its corresponding lever 0 0 0 each leverbeing provided with lateral arms g, which are engaged by thekey-plungers point and opposite the latter. The said pa-' per rolls androllers are mounted on any suitable carriage, as indicated at f, Fig. 1,capable of movement across the machine in the normal way. Any desiredform of ink-supplying mechanism may be provided, and the printing, whichis done by striking the paper against the inked type or against aninkingribbon interposed between the type and paper, may be accomplishedby any suitable mechanism such as is well known in the art. For example,I have shown a longitudinallymovable rod m arranged to strike the paperagainst the type, and thereby produce an impression, which rod m may bemoved at the proper time in any suitable way.

The operation of the machine just described is as follows: The operatorascertai'ns by inspection upon which keyboard is Located the key for thecharacter desired to be printed and then presses the treadle-lever tothe extent necessary to bring the frame or carrier containing the typefor such character to the plane of the printing-point. He then pressesdown the proper key, and thereby elevates the corresponding type-bar,the motion transmitted from the key to the type-bar being justsufficient, when the key is fully pressed down, to bring the desiredtype to the printing-point. At thismoment the rod m is operated to forcethe paper against the positioned type, whereby an impression of thedesired character is made upon the paper. Succeeding characters areprinted in the same way, it being understood that the paper is fed inthe proper direction and to the required extent by suitable mechanism atthe proper time.

As each key serves to position a series of type-barsviz. one type-bar oneach frame and as each of said type-bars is intended to carry differenttype, it is clear that each key will serve for positioning a pluralityof type characters. Hence it will be preferable to have each of saidcharacters which a key will position marked on said keys. One key somarked is shown on the middle keyboard in Fig. 2.

While I have described and shown a machine having four type-bar carriersor frames, each of which is provided with three typebars, it is to beunderstood that I do not limit my invention to these specific numbers ofcarriers or type-bars.

- Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a type-writer, the combination with a plurality of type-barcarriers and type-bars bodily and vertically movable therein, eachtype-bar having a plurality of type, of means for moving the carriers tothe plane of the printing-point, and means for moving the type-barsrelative to the carriers to bring the desired type on the type-bar tothe printingpoint.
